3.5mm headphone socket in the production of how to check and control, specific details we will give you a detailed introduction below.
3.5mm headphone socket check control
1. QA of Quality Department carries out spot check on products in delivery process, and accepts standard C=0 sampling plan.
2. Training the inspector once a year for inspecting the norms and Issuing the headphone socket with the certificate of induction after passing the examination.
3. Internal Inspection Sampling: In the process of inspection, team leaders conduct spot checks on the results of each inspection post within the regular time and distance, and give corrections and guidance on the spot.
4. Target management: set missed inspection targets for inspection posts, set general objective assessment methods for workshop, reflect and summarize monthly. It is necessary to sum up the increase and decrease of missed detection rate.
When single-phase grounding occurs on the user side, because the circuit breaker does not trip, in order to find the grounding point, it is necessary to pull the downline branches of the contract public line one by one, which will also cause the outage of the public line and increase the scale of the outage. The light touch switch is mainly assembled by the following parts after corresponding process treatment:
1. Plastic handle (material: POM material generally, if there is fire retardant, flame retardant and high temperature requirements, PA nylon material treatment process: injection moulding)
2. Insulation floor (raw material: bakelite; processing technology: stamping)
3. Terminals (raw material: generally phosphorus-copper; treatment process: silver plating)
4. Iron shell (raw material: generally iron; treatment process: through nickel plating or pot black process treatment, so as to avoid its oxidation)
